Cells must perform specific functions incoordination with other cells to make the human body work as it should. Previously, the ways in which cells learned how to communicate their intentions to other cells remained largely a mystery.
Some scientists have suggested that some cellscommunicate by creating and distributing hormones, while others use mechanical signaling. As part of a new study, biologists have identified a protein that plays an important role in the cell's perception of the environment.
The protein is called paxillin - it is formed onthe outside of cells and provides sensory information about nearby material. It also serves as an anchor for other materials with the help of a kind of climbing "crampons". Cats are metal plates with spikes attached to climbers' boots. They, in turn, allow the climber to secure his foot to rock or ice while climbing.
To better understand the role of paxillin in functionscells, the researchers conducted many experiments. This allowed them to see how it interacts with the environment in which the cell exists. The observations confirmed the scientists' theory - the protein helped cells perceive their environment and make the correct anchor movements when trying to travel.

Paxillin is a protein that is encoded in humansthe PXN genome. Paxillin is expressed in focal adhesion of non-striated cells and in costameres of striated muscle cells, and it acts to attach cells to the extracellular matrix.
